Conclusion
RFID
• RFID = Radio Frequency Identification
• Electronic labeling and wireless identification of objects using radio frequency
• Tag carries with its information
▫ a serial number
▫ Model number
▫ Color or any other imaginable data
• When these tags pass through a field generated by a compatible reader, they transmit this information back to the reader, thereby identifying the object
RFID components
• A basic RFID system consists of these components:
▫ A programmable RFID tag/inlay for storing item data; consisting of
an RFID chip for data storage
an antenna to facilitate communication with the RFID chip
▫ A reader/antenna system to interrogate the RFID inlay
▫ Application software and a host computer system
RFID Tag
• The RFID tag consists of an integrated circuit (IC) embedded in a thin film medium.
• Information stored in the memory of the RFID chip is transmitted by the antenna circuit embedded in the RFID inlay via radio frequencies, to an RFID reader
• 3 types▫ Passive▫ Semi-passive▫ Active
Types of RFID Tags
Active Tags
• Use a battery• communicate over
distances of several meters
Semi-passive Tags
• Contain built-in batteries to power the chip’s circuitry, resist interference and circumvent a lack of power from the reader signal due to long distance.
• They are different from active tags in that they only transmit data at the time a response is received
Passive Tags
• Derive their power from the field generated by the reader
• without having an active transmitter to transfer the information stored

Conclusion
• Positive
▫ RFID is a contactless reading technology and can read through other materials
▫ Hold more data than barcode does
▫ RFID tags data can be changed or added
▫ More effective, bring lots of convenience to us
• Negative
▫ Cost is relatively remain high (compare to barcode)
▫ RFID signals may have problems with some materials
▫ RFID standards are still being developed
